5.2.3 Timing Requirements (Memory Expansion Mode and Microprocessor
Mode)
Notes:
1. Calculated according to the BCLK frequency as follows:
2. Calculated according to the BCLK frequency as follows:
n is 1 for 1 wait setting, 2 for 2 waits setting and 3 for 3 waits setting.
3. Calculated according to the BCLK frequency as follows:
n is 2 for 2 waits setting, and 3 for 3 waits setting.
4. Calculated according to the BCLK frequency as follows:
n is 3 for 2
φ + 3φ, 4 for 2φ + 4φ, 4 for 3φ + 4φ, and 5 for 4φ + 5φ.
